Medellin, P.E. <br />Hydraulics Engineering <br />Overview <br />Mr. Medellin is a Senior Water Resources Engineer in the URS Water/ <br />Wastewater practice. He has over 13 years of experience in the fields of <br />hydrology and hydraulics, and has completed flood hazard analysis of <br />numerous project areas requiring this analysis as a prerequisite to <br />development of subdivisions. His role in flood hazard analysis includes <br />stochastic analysis of alluvial fans, 2- dimensional modeling using FLO- <br />2D, scour analysis, and hydraulic analysis of flood control channels. His <br />additional project experience involves drainage design and surface <br />modeling. A partial listing of his prior project experience includes <br />awareness floodplain mapping for the California Department of Water <br />Resources, and stormwater drainage system design and stormwater best <br />management practices (BMP) design for the California Department of <br />Transportation (Caltrans). He has experience working with HEC -RAS, <br />HEC -1, HEC -HMS, WSPGW, HEC- GeoRAS, HEC- GcoHMS, <br />Autodesk Civil 3D /AutoCAD, AES, Microstation, ArcView 3.3, ArcGIS <br />93, PondPack, and StormCAD. <br />Project Specific Experience <br />Senior Engineer, LAX Runway 61,2411 Safety Area and <br />Rehabilitation, Los Angeles, CA, Los Angeles World Airports, 2014: <br />Responsible for analyzing the pre- and post - development hydrologic and <br />hydraulic characteristics and evaluate the possible impacts to the existing <br />airport drainage system within the project area, including increased runoff <br />potential for project conditions. Performed one - dimensional hydraulic <br />analysis for box culvert extension within Argo Channel and designed <br />outlet protection. <br />77250 <br />Senior Engineer /Engineer -of- Records, Chatsworth Park South, <br />Chatsworth, CA, City of Los Angeles Department of Recreation and <br />Parks, 2013 - Present: Responsible for surface drainage component of <br />park redevelopment. The primary objective of this project was to develop <br />and implement a Remedial Action Plan (RAP) and improve surface <br />drainage of the site. Implemented several best management practices <br />including drainage improvements such as perimeter bio- swales to <br />minimize the potential for migration of sub - surface contaminates through <br />surface water, a network of detention basins to trap sediment and <br />modulate offsite surface water discharge, as well of design of several cross <br />culverts. <br />Senior Engineer, Vail Dam Seismic and Hydrologic Deficiency <br />Evaluation, Riverside County, CA, Rancho California Water <br />District, 2013 -2014: Completed hydrologic and hydraulic analyses for <br />existing arch dam of Vail Lake. Hydrologic and hydraulic analyses <br />included calculating the Probable Maximum Flood (PMF), routing the <br />flood through the reservoir via the existing spillways, overseeing the dam <br />break analysis, and providing remedial measures for the dam. <br />25F -76 <br />
